NEW JERSEY, ASSIGNORS TO NEW JERSEY OPTICAL (10., 0F NEWARK, NEW JERSEY,A CORPORATION OF new JERSEY.

To all whom it may concern:

Be it known that e, EDGAR R. DURGIN and WAYNE .S. SEARLES, citizens ofthe United States, and residents of Newark, county of Essex, State ofNew Jersey, have invented certain new and useful Improvements inEyeglass and Spectacle Mountings, of which the following isa'specification.

a Our invention has for its general object to provide an improvedconstruction of means whereby the lugs to which the temple wires aresecured and also the opposite ends of the bridges of eyeglasses andspectacles may be more efliciently and economically attached to the lensrims.

A further and more specific object of our invention is to provide meanswhereby such parts may be more securely attached and fastened to lensrims, particularly nonmetallic rims, than heretofore, as far as We areaware, has been practicable.

Our invention also has for one of its ob.- jects to provide an improvedconstruction of fastening or securing means which may beattached orfastened to non-metallic rims without injuring the same or biting intothematerial thereof in a manner to impair the strength and durabilitythereof.

Other objects and advantages of our invention will be referred to in thedetailed description thereof which follows or will be apparent from suchdescription.

In order that our invention may be more readily understood and .itspurposes and advantages more fully appreciated reference should be hadto the accompanying drawing in which We have illustrated one form of.

a convenient embodiment of our invention. It will be understood,however, that changes in the details of construction may be made Withinthe scope of the claims without departing from our invention.

In the drawings :Figure 1 is a s de elevation of a lens rim providedwith a device embodying our invention; Fig. 2 is a transverse sectiontaken on the line 2-2 of Fig. 1 and showing the inner edge of saiddevice attached to a lens rim; Fig. 3 is a transverse sectional view,enlarged, taken on the line 3- 3 of Figs. 2 and 4; Fig. 4 is a viewsimilar to thatshown in. Fig. 2 but With the parts considerablyenlarged; Fig. 5 1s a sectional view taken on the line 55 ofSpecification of Letters Patent.

Fig. 4; and Fig. 6 is a view of the parts entering into the constructionof our invention, said parts being separate from. each other and readyto be assembled.

In the construction as illustrated we have shown but a single'lens rimand a single attaching or fastening device embodying our invention butit will be. understood that one of these fastening devicesmay beemployed for each temple wire and also that two of such fasteningdevices may be employed in connection with each bridge or spring.

eferring to the drawings, a lens rim of non-metallic material having toreceive the edge of a lens and 2 designates an elongated part of sheetmetal bent and adapted to embrace a portion of the rim as illustrated.The said part 2 is curved longitudinally so as to conform to theperipheral curvature of the lens frame. Such curvature is bestillustrated in Figs. 1 and 5.

In transverse the device 2 is substantially of U-shape as illustrated inFig. 3. The inner edges of the part 2 are provided with undercutn0tches3 adapted to receive the projecting tongues 4 upon the oppositeedges of a cooperating complemental strip 5. The part upon the lens rimthe plate 5 is placed in position intermediate the inner edges of thepart or member 2 with the projecting tongues 4 in engagement with thenotches 3. After having been thus positioned the parts '2 and 5 areacted upon by a proper tool to bend the inner edges of the part 2 uponopposite sides of the notches 3 inwardly and slightly inner edges of therim upon opposite sides of the groove 1. The strip 5 is also bent orcurved both longitw.v dinally and transversely so as to cause it toconform to the groove 1 upon the inner side of the rim. After the parts2 and 5 have been pressed or otherwise caused to conform to andclamp therim at the point Where they surround thesame, the tongues 4 extendlaterally in directions transversely of the plane of the rim and aresituated in the said notches 3 in substantial alinement with theinwardly bent edges of the part 2. In the completed'st ructure the edgesof the device 2 intermediate the notches 3 are in abut.,

1 designates section the body portion of intermediate and outside of theprojecting tongues 4. The preferred relation of these abutting edges isshown at 10 in Fig. 3 of the drawing. It should be understood, however,that the relation of these edges may be changed without departing fromthe spirit and scope of our invention.

11 designates a stud or projection secured in any manner, as bysoldering, to the outer 'curved edge of the member 2. The stud 11 of therims of a pair of eyeglasses.

By the employment of our construction it will be observed that a portionof the rim is completely embraced or surrounded by means of the part 2and its cooperating and complemental strip or part These parts cooperateto form in effect a sleeve within which a portion of the eyeglass rim isheld, such sleeve conforming to the shape of the particular portion ofthe rim where it is situated. By thus providing means for completelyembracing the rim we are enabled to avoid the necessity of providingprongs or 'other parts which must be caused to bite into or becomeembedded in the material of the lens rim in order that the same may besecurely fastened or attached thereto. It is apparent, therefore, thatour invention constitutes a valuable improvement in that it preventsinjury in any way to or impairment of the eyeglass or spectacle rim.

We claim v 1. In an eyeglass mounting, the combination of a part bent soas to conform to a portion of an eyeglass or spectacle rim, the inneredge ofsaid part being provided with notches and a strip situatedbetween the edges of said part and having projecting tongues inengagement with the said notches.
